Drops of blood when I pee?

My boyfriend and I got a little frisky almost a week ago. Since then, we haven't done much more because I'm supposed to have my period - I'm on the pill. However its not coming this week (that's a whole other story). He fingered me, and went rather hard. To the point where it almost hurt.

Now I've been noticing that when I go to the bathroom, it stings to pee. Also, small drops of blood appear afterwards. None of this blood shows up in my underwear, its only when I use the bathroom.

It hurts quite a bit, and is very uncomfortable just when walking around. What could be the cause of this? Thanks!

Difficult to say. Normally, when a person has fissures as a result of rough sex, the only reason you know you have them is because of the urine and the burning sensation. This usually heals up in a few days. However, where you are actually seeing blood, it may take a little longer because it sounds like they are bigger, and because of this you should be careful of infection.
